Disable toc items based on build parameter

[ruffzy]

I am looking for a solution where I can change the generated output of a docfx build based on some parameters during build time. I have seen that there is a filter property in docfx.json where I can filter out some api stuff. But I would like to change the structure/content of my site which is generated from the toc.yml files.

The reason I would like to have this feature is that I generate the documentation specific for every customer we have. Based on the features a customer has registered on our product some pages of the static documentation have to appear and some pages should not be available for this customer.

Can someone please show me the direction where to look for?
